In their own words
CausewayOne Estimating
CausewayOne Estimating is web-based software for contractors and subcontractors handling bids and tenders. Estimators can build Bills of Quantities, assign resources and trades, and reuse standard pricing or earlier estimates. CAD/BIM Measure supports takeoffs from BIM, DWG, and PDF drawings, measuring areas, lengths, volumes, and curved or pitched surfaces. Drawing comparison, snapping, and custom scaling tools support measurement work. Subcontractor bids can be compared, with missing or deviant rates flagged automatically. Subcontractors access tender packages and submit prices, while estimators share revised drawings and specifications as addendums. Central document storage includes version control and audit trails, with documents assigned to trade packages. Causeway describes the platform as multi-user, cloud-native, and available from any device with an internet connection. Single Sign-On is available. The paid product was founded in 1999 and is headquartered in Buckinghamshire, United Kingdom; pricing is on request.
STACK
STACK is project software for working with plan pages, measurements and cost estimation. Its Free plan supports one active project per month, up to 300 plan pages, 50 measurements per project and one viewer seat. Premium and Pro list unlimited projects, plan pages, measurements and viewer seats, though neither plan has a listed price. STACK is freemium, with a free plan at free and a 7-day trial. It is available on Android, iOS, web and Windows. The company was founded in 2011 and is headquartered in Cincinnati, Ohio, USA. The listed plan details make the free tier’s project, page, measurement and seat allowances explicit; the two paid tiers specify the same unlimited allowances for those categories. Cost estimation is also listed as a capability.
